How to Remove Database from Suspect Mode in SQL Server 2012?

Summary: This post discusses why a database goes into SUSPECT mode. Also, it explains the methods to remove database from suspect mode in SQL Server 2012.

You may find a SQL Server database marked as SUSPECT if the transaction log file is damaged, preventing database recovery or a transaction from rolling back. The transaction log can get corrupted due to any of these reasons:

  • When the database was shut down abruptly and trying to access the database puts it in recovery. But, the recovery process fails due to corruption in data page or log record.
  • The database was running some operations when the SQL Server crashed leading to corruption that prevents a transaction from rolling back.

Besides the above-mentioned reasons, a database can be in SUSPECT state due to insufficient disk space, faulty hardware, or corruption of data files.

Whatever be the reason behind SUSPECT database, you will need to bring it online

How to Remove SQL Server Database from Suspect Mode?

Method 1 – Restore from Backup

Restoring database from the last good backup is the best approach to recover the suspect database without data loss. But if the backup is not updated or is damaged, skip to the next method.

Method 2 – Use EMERGENCY Mode to Fix the SUSPECT Database

Once the database is set to EMERGENCY mode, bring it to SINGLE-USER mode for running the repair process. Next, repair the database by using the “DBCC CHECKDB with REPAIR_ALLOW_DATA_LOSS”. Let’s discuss the complete process step by step in detail:

Step 1: Set Database into EMERGENCY Mode

Note: If you can’t set the database to EMERGENCY state, make the database OFFLINE and then bring it ONLINE again.

Step 2: Set Database into SINGLE_USER Mode

The EMERGENCY mode allows multiple users who are members of the sysadmin role to access the database. However, to run the repair process, you will need to put the database in SINGLE_USER mode and use ‘WITH ROLLBACK IMMEDIATE’ to roll back any uncommitted transactions. To do so, execute this query:

Step 3: Back up the Database

Now before running the repair process, back up your database with all the rolled back transactions. If anything goes wrong during db repair, you’ll have a backup you can restore to. 

Step 4: Repair the Database

Caution! Using the ‘REPAIR_ALLOW_DATA_LOSS’ involves risk of data loss. If the repair option find a corrupt record on a data page, it may delete that entire data page.

To repair the database, run this query:

Note: If running the DBCC CHECKDB with the repair option fails, chances are that your database is severely corrupted. Skip to the next solution to repair corrupt SQL database.

Step 5: Set the Database in MULTI_USER Mode

For this, execute this command:

Here’s the complete query you need to execute to remove database from SUSPECT mode and bring it to normal mode in SQL Server 2012:

Step 6: Refresh the Server

Once you’ve completed all of the above steps, make sure to refresh the database server.

Method 3 – Use a SQL Repair Tool

If the repair method can’t fix the damaged database or you can’t risk losing any data, try using a third-party SQL repair tool.

Use Stellar Repair for MS SQL software to bring your suspect database to its normal form without any data loss. The software provides an enhanced preview of the recoverable database objects. You can get back all the data you can see in the preview.


A database goes into suspect mode because of corruption that prevents transactions from rolling back. Or, when database recovery won’t complete due to corrupt log records or data pages. You can change the database from SUSPECT mode to NORMAL mode by restoring it from the last known good backup or set the database in EMERGENCY state and run DBCC CHECKDB with repair option – but use it as a last resort as it can result in data loss. A better alternative is to use a third-party SQL repair tool to regain access to your DB.

Product Review – Stellar Repair for MS SQL


My SQL Server 2008 R2 database was stuck in suspect mode. The database was no longer accessible. I tried restoring it by setting it to ‘EMERGENCY’ mode and then executed the DBCC CHECKDB command with REPAIR_ALLOW_DATA_LOSS option. Executing the query returned SQL error 8921. The complete error message reads:

Msg 8921, level 16, state 1, line 1
“CHECKTABLE terminated. A failure was detected while collecting facts. Possibly temp DB out of space or a system table is inconsistent. Check previous Errors.”

After some research, I found that the error occurs when the tempdb database runs out of space or the system tables are corrupted. The only solution I could find was to restore the database from backup. But, I didn’t have an updated backup available.


I decided to use a professional SQL database repair tool to fix database corruption. That’s when I came across Stellar Repair for MS SQL software.

What made me choose Stellar Repair for MS SQL?

The software offers remarkable features making it the most preferred SQL database repair software among users. Some of them are listed as below:

How to Restore MS SQL Database After Power Failure


If your company operates constantly (24/7) your servers are always on. Sometimes you may face power failure due to the maintenance of some power stations. In order to avoid electric power failure, my initial suggestion is you can setup backup power generators, battery backups also called UPS (Uninterruptible Power Source). Let me explore my experience with you. I’ve had a power failure. Suddenly, the power went out. A few seconds later when the power came on, I turned on, the server then I saw that my main database files were corrupted. Sometimes due to power failure, the hardware is expired or the database files will be removed automatically.

These database records are very important for us and we need to recover these records as soon as possible. If we don’t know the exact solution then what we will do? We will restart the server multiple time and it will take too much time. At some point, our database files are recovered but mostly the database files are not recovered with this method. When we try to open the database, we continuously receive a message from the system with corruption.


We don’t need to worry about it. In this article, I will show you multiple solutions that how we can handle all of these situations.

Solution 1:

In this solution, if we have the recent backup file of our database then we don’t need to worry. we can solve this problem using installed MS SQL Management Studio on the computer or server.

Follow the below steps to repair your corrupt SQL database:

Step 1: We need to run the MS SQL Management Studio and select the corrupted database.

Step 2: Do the right click on the selected database and you will see multiple options.

Step 3: We see that there are many options but I choose the options that are needed for the solution. We see that there are many options but I choose the options that are needed for the solution. After the right selection, we will see multiple options. Here we need to select the device because we have the backup file in our system (Computer).

Step 4: Here we can see that the right backup file is selected successfully.

Step 5: In step five or in the last step we just need to press the OK button then we will see that our database is restored successfully.

Solution 2:

In some cases, a CHECKDB T-SQL Command can be enough to repair the damaged database:

–You need to set the database to single-user mode first

–Then repair your database

–Once repaired, run this to return to multi-user mode:

Solution 3:

In this solution, we will use a software called Stellar Repair for MS SQL. Using this software, we can solve multiple problems in MS SQL Server. First, we need to download and install the SQL Database Repair Software. You need to follow few simple steps to repair the corrupt SQL database.

Step 1: This is the main interface of the software

Step 2: Select the corrupt MDF file

Step 3: Check the preview of all repairable database objects

Step 4: Stellar Repair for MS SQL allows the user to save the repaired file in the desired form. Here I’m storing my database file as an MDF file. For storing the database as an MDF file we need to select these options in the last small window. Then press the Save button. Our database file is stored successfully now we can open this database file in MS SQL Management Studio without any error message. You can also save your output file in more formats here you can see CSV, HTML, and XLS by selecting the option new database. If you find any error on this page during the selection you can refresh the window by pressing the refresh button.


In this article, we discussed how we can handle corruption in our database. There are multiple reasons but power failure is most of the common reason for database corruption. If we use the above solutions, I’m sure that we can solve these types of corruption in some minutes. If the problem is not solved with solution one, we need to try with the second solution.

Five ways to get OneDrive URL for a User in Microsoft 365

Database Filegroup(s) and Piecemeal Restores in MS SQL Server


Since SQL Server preserves data in a version, those facts need to move somewhere, but where does it shift? In which Filegroups come into play in SQL Server. These are the substantial files on your disc volumes that hold data and can be used for backup and administrative control purposes. An indispensable thing that comes along the way of the database is its security and protection that includes the restoration of the database too. Piecemeal restore process comprises a set of restore step sequences, initiating with the primary and, at least, one secondary read-write filegroups followed by read-only filegroups.


The first component to recognize is what types of files SQL Server makes use of:

The Primary Data File is the startup data file holding data in SQL Server and signals to other files present in your database. They have a .mdf extension on them.

Secondary Data Files hold all data that do not relate to the Primary Data File. They only hold user data, and so are user-defined Secondary Files are optional. Moreover, a secondary data file can be used to continue growing the size of the database if it rises above the limited capacity of a single windows file. The recommended extension for these files is a .ndf extension.

Transaction Log Files are the data files containing all logging actions available in the SQL server. Each database must contain at least one logging file. The recommended extension for these files is a .ldf extension.

All data files are preserved in the filegroups cataloged in the following table:

PrimaryThis is the default filegroup. This filegroup accommodates the primary files. All system tables are designated to the primary filegroup.
Memory-Optimized DataA memory-optimized filegroup is positioned on filestream filegroup
User-definedAny filegroup that is pointedly built by the user when the user first creates or later modifies the database.

Every database possesses a primary filegroup. This filegroup has the primary data file and any secondary files that are not part of any other filegroups. User-defined filegroups can be created to categorize data files together for administrative, data allocation, and placement means. For instance, let there are three files named file1.ndf, file2.ndf, and file3.ndf, built on three disk drives, respectively, and appointed to the filegroup named fgroup1. A table can then be created explicitly on the filegroup i.e. fgroup1. The three disks will advance queries for data from the table; this will enhance performance. The same performance enhancement can be achieved by using only one file created on a RAID (redundant array of independent disks) stripe set. However, files and filegroups enable you to add new data to new discs easily.

Rules to be considered while designing Filegroups:

  • A filegroup can be used by only one database. For example, file data.mdf and data.ndf, which has data and objects from the sales database, can be used by only one database.
  • A file can be associated with only one filegroup.
  • Transaction log files can never be a part of any filegroups. Transaction log files can never be a part of any filegroups.

Sometimes, a database restore from the backup is desired. As we know, we do have the choice to restore needed file groups, but not all of the filegroups are needed to make the database online at a specific time. It is always enforced to recover the primary filegroup, but any secondary user-defined file groups are optional, at that instance, while doing the restoration. We can obtain partial data as it is available online after restoring it. We have to wait for the rest of the data to recover other filegroups.

The command RESTORE DATABASE with PARTIAL clause initiates a new piecemeal restore operation. The keyword PARTIAL points that the restore process includes a partial recovery. The partial keyword indicates and starts the partial-restore sequence. This will be validated and authorized during the restoration stages. As the database recovery has been delayed or postponed, so the position of the database remains pending.

To test the concept of piecemeal process, do follow the following steps:

  1. Add another filegroup to preserve the static data. Add a table to the filegroup and insert a few records.
  2. Query the table to validate or authorize the data
  3. To change the filegroup state to read-only, use the “alter” database command and backup the database.
  4. The database has three filegroups, one is read-only, and the other two are in read-write mode. Verify the filegroup status by executing T-SQL and backup the read-only database.
  5. Drop the database to mimic the piecemeal recovery process of the database.
  6. Perform the database restore operation before you start changing the session context to the master database. Now, we are going to do the read-write filegroups restore using the READ_WRITE_FILEGROUPS clause.
  7. Next, restore the read-only filegroups and verify the output by querying the read-only table data.


Preserving data file groups and database-recovery and healing processes to the requirements of the organization is crucial. For instance, let our SQL Server crashes then we are unable to bring this server up, now we need to recover databases on a separate server and bring them online. The database is enormous, and so recovery might take a few hours to finish. Here the Piecemeal database works. In this technique, we can recover the database on a filegroup level and can minimize the downtime outstandingly.

OneDrive Sync issue: SharePoint Documents Library not syncing

OneDrive sync issue are quite common which stops content from syncing to from local drive to OneDrive and from OneDrive to local drive. There many resultions listed on different blog posts.


I have recently faced a strange issue where OneDrive for Business Sync client is not working for 3 users, they all syncing content from same document library, there were more users who were sync content from same document library but no issue for them. The sync client halts on few files and do not sync any other content from other libraries and User’s OneDrive.


We have taken multiple steps to troubleshoot the issue which are listed below:

  • Verified the sync client version for all users
  • Sync library on my laptop and it synced without any issue but now working on user’s machine
  • Stopped synced and start sync again from same library
  • Unlink the user account from OneDrive and sing in back but still having the same issue
  • Restarted the user machine
  • Executed the OneDrive reset using %localappdata%\Microsoft\OneDrive\onedrive.exe /reset but still having the same issue.


The issue resolution was quite simple and we should have done that as very first step during troubleshooting. We went to the document library of one of the user who having issue and followed the below steps

  • Stopped folder sync on the OneDrive client for the folder which causing issues
  • Synced the folder again from SharePoint document library and on the syncing screen we selected “Create a new folder” instead of User this folder.
  • And sync started working without any issue.

The actual issue was with some file which synced on local drives of the which got corrupted for unknow reason (no idea why) and every time when we have started sync it paused the whole sync process after syncing few files.

Below are few useful links to troubleshoot the OneDrive client syncing issue:

Process to Restore SQL Database From Backup In Single User Mode

SQL Server from Microsoft is one of the best and vastly used relational database management system. This application can be used to organize and maintain data. To deal with this powerful application proficiency and experienced are required in Every database administrator.

How to fix SQL database corruption after power outage


Sometimes due to the power outage or power shortage, we have to face some hardware or software issues regarding our system (computer). And when you log in again on the system afterward, you see that your most important SQL Server database data is not available. This database is so important to you that your all business accounting and financial records saved in it. One and only one solution remains when he/she has to face this kind of problem. And this solution is to reboot the system many times, sometimes it works, but the working probability of this solution is too low. And system always shows the disputable message that the database not found or corrupted. And sometimes you contact the service provider, and they said this software version is no longer supported. We will show some scenarios through which we can solve this corruption issue. After these scenarios and at the end of this article I will suggest you a software which will solve all your problems with only one to two clicks.

Power out problems

Depending on your production environment, you may have some Power out problems due to this, the server may be shut down, and the database can be corrupt. For this scenario, try to have a UPS for your server or a battery backup system.


While searching for a solution, the first solution is to have a recent backup of your most important database if you have this one then don’t worry about it. Your SQL server is smart enough to tackle this of problems. It automatically recovers your corrupted database with the help of SSIS or some scripts and saves your entire database but, in case if you have no recent backups now this time you should worry about that you are going to face a huge loss because your database has all kind of transaction and financial records of your business.

Torn Page detected

What is Torn page?

It is a setting to detect database corruption in SQL Server.

It detects failures related to I/O headers that try to access a page that has miswritten to the disk. It reports an I/O message an error (torn page) detected throughout the reading.

Afterward, while searching for a solution when you have no recent backups for your database. You can take a copy of MDF and LDF

Hex editor:

What is the hex editor?

A hex editor allows checking the manipulation of the elemental binary information that constitutes a data file. There are several hex editors on the web that are free like UltraEdit, HxD, BVI, etc.

You find that a table sys.allocation_units which was the part of your database. You can use the hex editors to verify the data corrupted and using the page number edit the data and fix it:

Proposed Solution:

Detach the repaired database from the failing environment. Copy the MDF and LDF files back to the customer’s environment. Recommended scripting the entire database with data and recreating to get it back to a safer position.

Another way to repair is by using the T-SQL commands. You can use the DBCC CHECKDB to check consistency errors in the database and also you can repair your database.

For more information about the DBCC CHECKDB commands, please refer to this link: DBCC CHECKDB (Transaction-SQL)

SharePoint Online: Classic Vs Modern Search

In this blog post I will try to share the difference between Classic and Moder search in SharePoint online. Search administrators can customize the classic search experience but can do much on modern search as there are not separate search settings for the modern search experience. But certain of the classic search settings also apply to the modern search experience.

Classic sites have classic search boxes and modern sites have modern search boxes. If you believe that modern search gives your users the best experience, influence your organization to start using modern sites.

  Classic Search Modern Search
Search locations Search Center
Publishing sites
Classic team sites  
Hub sites
Modern team sites
Communication sites
SharePoint home page  
Search result Same search resultPersonal search result
Search experience Submit query to see search results Search results show up before typing and update as you type
Search result page Customizable Non-Customizable
Search settings Crawl site content Search
Schema Result source
Remove a search result
Promoted result
Site level search settings
Custom search results (display template, search web parts, query rules) 
Crawl site content
Search schema (except sortable, refinable, company name extraction)
Result source (Tenant level)
Remove search results
Promoted result (only when search across all of Share­Point)

I personally do no prefer customization on Search if there is no specific business need but if there are requirements to customize the search experience as per the business needs and user experience. If you are going to migrate from classic site to modern site then your search customizations will be impacted because as I mentioned earlier in the blog post, classic site has a classic search box and you’ve set up the search box to redirect to a custom Search Center to show results that are filtered and formatted for organization-specific content types. The modern site has a modern search box and you can’t customize the modern search experience. If you don’t need to customize search, we recommend using modern sites.
